IMPROVED LEATHER-ROLLER.

Specification forming part of Letters Patent No. 50,079, dated September19, 1865.

.'o all whom it may concern.-

Be it known that 1,DAv1D H. PRIEST, of Vatertown, in the county ofMiddlesex and State of Massachusetts, have invented a new and usefulMachinefor Rolling Hides of Leather, called the American Leather-Roller;7 and I do hereby declare that the following is a full and exactdescription of the same, reference being had to the accompanyingdrawings and the letters of reference marked thereon, making a part ofthis specication, of which- Figure l is a transverse section throughtoggles of the machine. Fig. 2 is a side view of the same. Fig. 3 is alongitudinal section of the same. Fig. et is a section of the tworollers and the table.

A represents the frame of the machine; B, the movable or self-adjustingtable 5 C, the leather roller or drum; a, its clamp-bar; b, itsbearings; D, the lower feed-roller; o o, rockerlevers, e e, their shortarms; f j, their long arms; d d, their shafts; g g, their toggles, h,the guide-plate 5 l, its slot; fi, its slider; j, the spring, k, the eyeor hook m, the thumb-screw ofthe guide-plate.

Now, in order that others may better understand the nature and use of myinvention and be enabled to construct the same, I will proceed toexplain it.

It is well known that in rolling together hides for transportation thathave just been tanned, it requires several men to work to advantage,that the work itself is laborious, that in the ordinary way the rollscannot be made compact, and that necessarily, in thus packing, largeholes are left in the middle of the rolls, for which the merchant has topay the carrier in transportation or trucking as much as for the spaceoccupied bythe solid leather, so that packing becomes a matter of nolittle moment to the merchant as well as the carrier.

Now, in order that hides may be packed more easily, occupy less space,with less likelihood of drying, and in every way be better fortransportation, I have invented my machine, and its mode of use I willnow explain.

Referring to each of the gures in the accompanying drawings, a movableor self-adjusting table will be perceived, (marked B.) N ow, this tablerests on four levers, the short arms of which are marked e,respectively, as seen in Figs. 1, 2, and 3, and the long arms c on oneside of the table connected with the toggles g g. These toggles areriveted to or fastened to the slide z', which plays in the slot l, andis adjusted by the thumb screw m. Through the eye or hook kin this slidepasses the spring j, which is made of rubber or any suitable elasticmaterial, the ends of which are fastened in the manner seen in Figs. 2and 3, or in any convenient manner. This table is also secured in itsplace by the bearin gs b, which support the leather-roller, as seen inFigs. 2 and 4, it being out into sufficiently to admit the same; and thebearings are secured by the screw and nut on the under side of theframe. There is also let into this table, in a line with the leatherroller or drum, another roller, D, called the feed-roller, as seen inFig. 4, and this roller may be made to turn or may be stationary. Theleather-roller O is supported by the bearings in the manner seen inFig..4.,and is turned by a hand-crank. This roller also might be turnedby a crank connected with gearin gs, by which greater power might beobtained. This drum C also has a clamp-bar, (marked a, seen in Fig. 4,)being a small longitudinal section of the drum, secured at one end by afixed band and at the other bya movable band, so that the bar can beeasily taken out when necessary. The shafts d d, the ends of which areseen in Figs. 2 and 3, also are secured in the frame, but so as to rollwhen the table is pressed down, and the four levers are secured to theseby screws, in the manner seen in Fig. 3.

The under side of the table, where it rests upon the levers, may beprotected by some metallic or other substance to prevent Wearing.

Now, to work the machine, let it be put in order, as seen in Figs.2 and3, turn the thumbscrew so as to allow the spring to press the table,with its feed-roller, up under the drum,fasten one end of thehideundertheclamp.bar,andturn the crank. When one hide is partially rolledshingle on another, pressing one end, as before, under the roller, andso on until a roll of sufficient size is obtained. The table beinggradually pressed down upon the levers and held by thevspring, anyconvenient-sized roll may be obtained. Remove the pin seen in thebearing in Fig. 2, 'turn the drum on the bearing next the crank, itbeing movable in its position, until it passes off' tbe side of thetable, and the roll,being secured by strings,is easily drawn off thedrum. y

Now, I do not confine myself to the use of the clampbar b, as describedabove; but I may use for the same purpose the drum divided through itscenter as far as the bearing next the crank, and secure the hide betweenits parts 5 or the clamp-bar at one end may be seourely fastened. I alsoclaim for the same purposeI may use the same arrangement of rollers andsprings with thefbearings fastened tothe door, Without the table.

What I claim7 and. desire to secure by Letters Patent, is-

1. So applying the adjustable table as to allow it to rise and fallautomatically with the
